I am a longtime lurker and love the board, especially the pics! Here's my question: I am a Federal Agent and currently own a postban AR-15 which I purchased privately. I would like to put a collapsible stock on it and a flash suppressor. The postban weapon is not really for duty use in the sense that I do not carry it for raids, etc. as I am issued an actual M-4 or SMG for these purposes when the need arises (in other words, the M-4 and SMG are not take home items).

However, the postban AR CAN be articulated to be used for duty in the sense that I practice with it on my own to remain proficient (like I said, the M-4 is not a take home item). I simply want my personal AR to be configured as close to my agency's M-4's (sans full auto of course) as possible. Anyone have any ideas on this one or would I just be better off buying a LEO only lower. Thanks!

LEO weapons are only legally purchased/reconfigured for use as a duty weapon, and must have a letter from the chief stating so. If you have letter from your chief, you can personally purchase whatever you want, but if you leave the dept. you cant take the rifle with you. You do not need a LEO marked lower. The PO or letter used for the purchase (which is attached to the 4473) allows you to add any stock/flash hider/bayonet lug you want. This is how it was explined to me, by my ATF inspector.
